This evening, I upgraded to the latest v7.4.4.1.
On the application startup, I'm now getting an error window:

SplitCam error
Cannot change media format: 0x80040200

By clicking OK, the popup closes, and the application finishes to start, initializes and seems to work correctly.
But it's very annoying to have to confirm a popup each time the app starts, that's to say at each computer boot !

Yes, it was the full log !
But indeed, as I told you, as v7.4.4.1 was buggy, I reinstalled the old v7.2.4.1...
I thought it would keep the log between the versions.
Clearly not, that's perhaps why you didn't find what you were expecting !
